Sunday, July 1, and the official opening of the meeting Monday morning, July 2. During the six day conference a wide variety of topics
will be discussed in the morning plenary sessions beginning with mathematical topics on Monday, quantum aspects of gravity on Tuesday,
precision tests of general relativity on Wednesday, relativistic astrophysics on Thursday, cosmology and astroparticle physics on Friday
and the latest scientific news and the history of physics Saturday. There will be five plenary lectures each morning and up to twenty
parallel sessions in the four weekday afternoons excluding Wednesday, which is left free for a trip and the evening conference banquet.

IUPAP Declaration (http://www.iupap.org/):
Freedom of Movement for Scientists.
The Marcel Grossman Meetings were founded with the premise that scientists of all nations have a right to meet to exchange knowledge independent
of national borders. As such we affirm the IUPAP declaration:
"To secure IUPAP sponsorship, the organizers have provided assurance that MG13 will be conducted in accordance with IUPAP principles as stated
in the IUPAP resolution passed by the General Assembly in 2008. In particular, no bona fide scientist will be excluded from participation on the
grounds of national origin, nationality, or political considerations unrelated to science."

As more information becomes available, it will be posted on this web site, now in its preliminary phase.
